The Bosch Rexroth 3WRCE 50 V000P-2X/SG24K31/C5M-118 (R901101462) is a high-response directional control valve designed for precise control of flow and direction in hydraulic systems. This advanced valve is part of the WRCE series, known for their reliability and performance in controlling the quantity and direction of flow, primarily within control loops. The 3WRCE valve comprises a stage pilot control valve with a dry torque motor, a low-friction nozzle flapper plate amplifier, mechanical feedback for spool position, a main stage for regulating flow, an inductive position transducer attached to the spool's third stage, and integrated control electronics. The function of this valve involves comparing command values with actual values through its integrated or external electronics. The proportional current actuates the torque motor based on this comparison, which in turn proportionally controls the pilot valve's position. This process manages the flow into and out of control chambers A and B that actuate the main spool up to the point where there is zero control deviation. Noteworthy features include factory-set opening points for the V spool that can be adjusted post-installation using zero adjustment potentiometers. During component exchanges such as that of the pilot valve or electronics, no additional settings are required except for this zero adjustment. In case of power failure, the pilot pressure is connected to control chamber B by design, ensuring that P to A is closed. This Bosch Rexroth valve excels in applications requiring precise position, pressure, force, or velocity controls such as presses, die casting machines, and nibbling axes. Its block installation design makes it suitable for various industrial applications where high responsiveness and accuracy are crucial. The integrated electronics feature an offset to compensate for any trimming discrepancies in pilot pressure during operation or after tool changes.
